I kept the tune in when doing emission tests in Ohio and Maryland. It passed both times.

That's exactly what I would have suspected. If anything, the tune will give you a bit of extra ignition advance, which should give you a hotter and cleaner burn, theoretically.

Yeah tune should never have a effect as long as your check engine light is not on, though some of these guys who went catless / stage 2 have check engine lights on that can’t pass. Like pennsiveguy mentioned it will actually help in most cases, and believe it or not your mpg will actually go up , only trouble is it’s pretty hard to achieve that because who the hell with a tune on the vehicle is actually going drive the car like there grandmother.

This thread still alive?
Want to do a bm3 tune on my 2017 x5. Anything else I’ll need? Saw that some guys changed spark plugs and air filters from reading the thread. Car I just got has only 16k miles. Want to do a dyno before and after the tune. Anyone in Chicago area that could recommend a good place to do it? |

After flashing, give it a half a tank of gas to let the car adapt to the tune, then do some data logging of a full throttle pull or two through a couple of gears (DSC/DTC fully off). Then open a support ticket with Pro Tuning Freaks and ask them to look at the logs. They tweaked the tune for me 4 times to dial it into my car. It's not the same as a custom tune, but it does dial it in a bit for your actual vehicle. If you plan to dyno, definitely get a baseline before the tune so you have something to compare it to. And use the same dyno for all runs. Let us know how you make out. |

How do you know your update? Weighing up selling mine or modding it some more...

2017 x5 50i with 73k on the odometer
- installed ngk 97506 gapped to .02 (is this too narrow)? - installed catless downpipes - installed x5m air filters - flashed bootmod3 stage 2 93octane tune I am seeing some superknocking on cylinder 1,4,5 on a wide open throttle pull. Going to flash back to stock and re-test. For some reason the datalog isn't running within bootmod3 on my laptop, waiting for their support reply and looking for other suggestions. |

Notice I have some knocks on hwy at 8th gear at around 2500rpm accelerating moderately (normal hwy driving type, not WOT). I first noticed it was during rain when trying to accelerate to pas cars in front of me so I thought it was traction control kicking in but it also happens when road is dry so it's not traction issue. No problem when I do WOT and kick down. The engine rev smoothly all the way to redline at lower gear. No trouble at 6th gear doing similar mild acceleration at 2500rpm.
Mods: BM3 stage 1 X5M filter replaced less than 1000 miles ago Oil changed less than 1000 miles ago Spark plugs changed 28k miles ago Car is at 69k miles Thinking to switch back to stock tune to see if this issue remains but it always takes 5-7 tries each time to switch..... Never had this happened before. Any idea/suggestion what cause this? Thank you!

I want to caution everyone with knocking issues to not WOT until you guys sort all the issues with it, because you might get rods bend and it'll be too late then - at the very minimum you'll be looking at long block replacement with labor - I mean who needs that kind of headache?
Just take it easy and sort it out. I would NOT recommend going Stage 2 on n63tu on x5 f15. Guys Stage 1 is enough (and risky by itself). There is no need to go all in and increase risk of bending rod with Stage 2. This might be unpopular post here, but hey just my 2cents. I know 2 people from this forum who had to replace engine due to bent rod after going Stage 2 and then WOT on highway. You are pushing it too close to the limit. With boost levels on Stage 2 and WOT - you are a hair split away from ANY hiccup that will be the tipping point. By ANY hiccup I mean if during WOT you'll get misfire (as an example) - at this point long block replacement with labor probably will cost more than F15 x5 itself costs nowadays. |

I don't have any direct experience with your issue, but it could be the gas. Even gas from high quality stations is sometimes not the best with it comes to overall octane. Additionally, the BM3 93 octane maps may be a bit too aggressive. I'm running Shell V-Power 93 exclusively and even I had some timing reduction on the Stage 1 91 map. I can't imagine how much reduction I'd have on the 93 map. PTF was able to tweak the OTS map for me to make it run better. After you flash to stock and verify no problems, try flashing Stage 2 91 octane and see if you have the same problem. You could also try running the fuel tank a bit low and putting in a splash of race gas (if you can find it) to increase overall octane. It's not a long term solution, but it may tell you pretty quickly if you have an octane problem (or if the tune is too aggressive for your engine/mods). Quote:

Ok, one thing I did wrong was not tighten the spark plugs down enough, but I also installed eight new coils, then did a base stock tune log, stage one and then stage two 93. After I had all that I sent to PTF and we went through two revisions of tweaking the tune. Might schedule a dyno pull to see what numbers it reads out, but - it's quick.

Any car with over 20k miles bought used, should always get spark plugs changed before you tune along with an oil change as just preventative maintenance if you do not have records of when it was last done
Futhermore, do not use BMW OEM oil on these V8 0w30 is not recommended for any Tuned vehicles especially in the summer months. Stick to a BMW-LL01 certified oil 5w40 stg1 (Liqui Moly, Amsoil, Motul X-Cess) Pennzoil and 5w50 (Amsoil or Redline) if your ambient temp is over 80F and Stg2 tune.

Please disregard Picasso, he must be new to tuning and has been spreading unneeded info.
These cars can handle any stage you want depending on how the tune is developed. The stock turbos don't have enough boost to pop your engine. The only way you are bending a rod is through hydrolock, bad tune(poor fueling/timing/etc) , poor octane, or bad maintenance. A proper tune that adds 150hp/tq is not problem for the TU. I guarantee the people you know either had bad tunes or beat the hell out of the car and maintained them poorly. |

Sorry guys I don't have a F15/F16 50i (do have X6 35i however) but I figured I'd chime in here since I do have N63TU1 BM3 Stage 2 (650i GC) and the 6 series forums are kinda quiet.
Bootmod3 Stage 2 93oct ARM Catless DP Muffler Delete Tried a ~20% E85 blend Went to 1/4 track and best time was 12.822 @115MPH, very disappointed. Somethings gotta be up right? Used launch control every run and I consistently ran 12.8/9. IAT's were constantly 40-50F above ambient (80F) and it was very humid outside. I dont have any proper logs but according to Bimmerlink I was hitting 19psi max during the run. I'm gonna build a custom intake and hope that helps for next time :\ Last edited by itzjoker; 09-24-2020 at 09:48 AM.. |

I feel like the car isn't performing at its full potential due to weather or something. On paper these run 13.1 stock so it's hard to believe that BM3 Stage 2 only improved it by .2-.3 seconds when I'm seeing a bunch of 550xi's run low 12 high 11 with same mods. |

That trap you should run high 11’s - low 12’s , how is your launch , is it bogging or spinning too much?

No spin or any noticeable bogging using launch control. I attached my best times that night (right side). Not sure how my other times are though.
